of which the-following isa specification;

My invention relates to new and: useful improvements in combustion accelerators,

andhas for its objectto provide an exceedingly simple and efiective device of this character which may be readily and quickly applied to the lid? supporting bridge of a stove o'r ran'geg so that air may be taken" into the same and raised to'tv verynliighltempera t'ur, and then delivered to the fireyabove the same wherethissuperheated air will colnming l'e and mix with the flame" from the fire and: the gases'thrown' oft thereby, so as to greatly" accelerate the combustion and consume the smoke producingielements;

A further objlectiof the: inventionvisi to provide a: combustion accelerator which will be supportedfiby" the bridge and depend therefrom so that theair' therein will be" r'iised to: a" highitemperature, before being djel 'ered through" outlet" openings: in the form of" small perforations or slots" at the efid fo'f the-devioea- A still' fu'rther' Qb'j'cti oi the invention is to prov-idea supporting means havingiam iii-1st opening therethroughwhereby'the at mo'sph'eric' air will beer-awn into the device by-i't'he t through the stove and chimney:

A still further obj ect? of the. invention is b provide a? device for attachment to; the brid which is a: part of" the stove/"seldom rem v e or clisturbedg'; said'bridge, because of its do'wnw a rcllv projectingaflanges which ij lrold'the stove-lids; protecting the attached:

device against" disturbances caused byat- 1 A still further"object of the invention is to provi'd device of the titlestateduwhich: when" extend-ply consideredis 'arcua't'e trans ve'rsely, so that very small snrface' o-f the device is in contact with the supporting bridge, thereby permitting theheat to circu'late entirelyaroundthe device and come" in contact with nearly the erfti relv surface of the supporting bridge which will tend to more quickly heat the air withinthe device and prevent the bridge-'froin being cooled oil, which would make this portion of the stove useless.

consists in: the details" oii construction and: combination of elements: hereinafter set forth. and then specificallydesignatedby the claim." 7 Q In: order that those: skilled in the'art': to which: this inventionappertains may understand how to make and use the samegl Will describe its construction in detail, referring by numeralstothe accompanying drawing forming a part of this application, in which F igure 1, is a plauview of a" stove: or range showing the position of this device in dotted lines. Fig. 2 is an' enlargedside elevation 'of my' iinprovedi combustion accelerator showing the supportingfibridge insection. Fig.7 3; is a bottom view thereof. Fig; l, is a plan view of the' combustion: accelerator IGIYIOVGd fromthe supporting bridgm Fig. 5, is a sectionat the lin'e 5.5

which depend fromwoppos'ite edges of the supporting? bridge;

In the supporting, bridge' is formed. an! opening fit preferablycf two diameters, the larger diameter adapted: to receive the: head: 7 offltlre supporting screw 8', so tliatct'he outer face of the head of" said screw waits flush with the: outer surface of the. support-"- ing bridge to" eliminate projections which ire objectionable' because. of their interfer nice with cooking utensils placed' upon the stove; Thisfscrew' is providedwith a central opening-9 passingrentirely!therethrough, and the head of said sj crew"hasslots or grooves 10"f0r1n'ed1 therein in communication with theo'p'ening 9; M

11 denotes a casing comprising a fiflthbOt toniwall 12, arch wall 13, andend walls 14; the arch wall where it connects with the bottom wall and" intermediate its ends being concavo-convexyso as to conform approximately to the shape of the supporting bridge 3. The archwall of the casing is providedwith a boss 15 in which is formed a threaded inlet opening 16 into which the sames iethreaded for s pporting the" cas ing from the supporting bridge 3, and in order to prevent the casing from movlng about I provide a pair of spaced integral upwardly projecting lugs 17 formed ith the arch wall adjacent one end'of the casing and situated some distance from the supporting screw, said lugs adapted to engage the underface of the supporting bridge 3, and because of the unevenness of the under or inner face'of the supporting bridge, said lugs will be prevented fro-m sliding or moving about over the surface of the supporting bridge when the casing is drawn tightly against the supporting bridge. The boss 15 and lugs 17 space the casing from the supporting bridge for the passage of the heat, whereby all of the walls of the casing will be heated, and so that the proper temperature will be maintained upon the supporting bridge, whereby this part of the stove may be used for cooking purposes as well as any other portion thereof.

The air after passing into the heating chamber 18 in the casing and being raised to a high temperature is then sprayed or projected into the flame through the outlet openings 19 preferably formed adjacent each end of the casing. either in the bottom wall 12 or a portion of the arch wall 13 or both, and these outlet openings may be in the form of small holes or slots. In pract ce a hole 6 is formed in the supporting bridge 3 or if found desirable any other portion of the stove and the casing 11 is-placed beneath the same, so that the threaded opening 16 is in alinement with the opening 6, at which time the screw 8 is passed through the opening 6 and threaded into the opening 16, which will draw the casing against that part of the stove to which it is attached, where it will be firmly held against accidental displacement.

In'placing the screw 8 in pos tion the slots 10 may be used as a screw driver slot. When the device is properly placed in position, atmospheric air will be drawn into the heating chamber 18 through the inlet opening 9 in the screw 8, where it will be raised to a very high temperature which will also increase the pressure, said pressure causing the super-heated air to be forced through the outlet openings 19 into the flame of the fire, thereby adding sufficient oxygen to the mon-oxid thrown off by the fi e to produce a combustible gas which will immediatelv ignite and consume the foreign matter which generally passes up the chimney as smoke, and the combustion of thi gas will also raise the temperature within the stove so as to greatly in-' crease the efliciency of said stove.

Because of the construction of the casing 11 the heat is allowed to pass entirely around Copies thispatent nay be obtained ton ve cents each, i aqdggwnhgge renes patents said casing and to also come in contact with the supporting bridge 3,'thus effectually heating the air within the heating chamber 18 as well as the supporting bridge 3, which is essential to the efficiency of the stove, for if any considerable amount of the surface of the supporting bridge is covered by the device, the temperature of said supporting bridge would be lowered and the efficiency of the stove greatly decreased.

As hereinafter described the outer face of the head 7 of the screw 8 is preferably flush with the outer face of the supporting bridge 3, so that there are no projections to interfere with the cook-utensils upon the stove and the head of said screw is provided with slots or grooves 10 leading from the outer circumference there f to the inlet opening 9, so that if a cooking utensil is placed upon the stove and covers the inlet opening 9. but not both of the grooves 10, the air will pass through said unco ered groove 10, then through the inlet opening 9 and into the heat chamber 18.

Of course I do not wish to be limited to i the exact details of construction as herein shown, as these may be varied within the limits of the appended claim without departing from the spirit of my invention:

Having thus described my invention, what I claim as new and useful, is-

A combustion accelerator com rising a casing consistlng of a Hat or straight bottom wall having outlet openings adiacent each end. end walls and an arch Wall, said arch wall being concavo-convex where itjoins the bottom wall and provided with a threaded opening leading to the interior of the casing, upwardly projecting integral lugs formed with the arch wall of the casing, a supporting bridge to which the casing is to be secured, said supporting bridge having an opening therein of two diameters,and a screw provided with a head and having a 1" longitudinal inlet opening passlng therethrough, said screw adapted to be'passed through theqopening in the supporting bridge, and mounted in the threaded opening in the casing for drawing the casing against the u'nderface of the supporting Subscribing witnesses.
